RAILS                  
                                          
                                          
  
                                          
  
                                          
                                          
 TRAINS  ARE  SO  CONSTRUCTED  THAT  THEY 
 HAVE TO FOLLOW A SET PATH. THIS PATH  IS 
 CALLED A  "RAILWAY",  WHICH IS COMPRISED 
 OF TWO METAL RAILS,  HENCE ITS NICKNAME. 
                                          
 BECAUSE  THE LOW  FRICTION  BETWEEN  THE 
 WHEELS OF THE TRAIN  AND THE RAIL METAL, 
 THERE  ARE LIMITS FOR  HOW ACUTE A CURVE 
 CAN BE,  AND EVEN  MORE SO FOR  HOW MUCH 
 THE  GROUND  UNDER  THE  RAILS  CAN   BE 
 SLOPED. THUS A RAILWAY IS  OFTEN NOT LED 
 ON TOP OF HILLS, RATHER THROUGH  THEM IN 
 TUNNELS  (IF   THEY   ARE   LARGE),   OR 
            ARTIFICIAL CHASMS.            
                                          
 THERE WILL BE TREES  ON THE SIDE OF  THE 
 RAILS, BUT NOT  TOO CLOSE, OR THEY  WILL 
 BE  CUT DOWN  BY THE  RAILWAY  JANITORS. 
 THERE  WILL  BE  PLAINS,  AND  BODIES OF 
                  WATER.                  
                                          
 TRAINS GO  BY  DAY AND  BY NIGHT.  ALONG 
       THE WAY, THERE IS INFORMATION      
 SCATTERED,  OFTEN  PUT  ON TOP OF POLES, 
 TO BE INTERPRETED BY THE TRAIN  DRIVERS. 
 DIFFERENT  PARTS  OF  THE  RAILWAY  HAVE 
         DIFFERENT SPEED LIMITS.          
                                          
 SOMETIMES, TRAINS  HAVE TO STOP AND WAIT 
 FOR SOMETHING TO HAPPEN,  FAR AWAY. THIS 
 IS  SIGNALED  BY  RED  OR GREEN  LIGHTS. 
                                          
                                  
                                          
 MANY  PEOPLE  FOLLOW THE RAILS  BY FOOT. 
 OFTEN  THIS  PROVES  TO  BE  THE SHORTER 
 PATH BETWEEN  TWO  POINTS. HOWEVER  THIS 
 IS  FROWNED   UPON,  AND  VERY  IMPOLITE 
        TOWARD THE TRAIN DRIVERS!
